Looking for a 2 bedroom (possibly 3) flat or house (Ho Chi Minh City)

Hi, My boyfriend and I have just arrived in Ho Chi Minh City and are looking for a 2 bedroom apartment or house. We are open to different options (3 bedrooms would be ok for a house) and are looking around Phu Nhuan or Bin Tanh districts. We would like to live in a vietnamese part rather than an expat area and would rather a house than a flat in a tall apartment complex.Budget is $500 max.. Anyone knows of anything? Many thanks, Noémie&Tanc
